Hello, years ago in this message board paul wrote how to replace QS LCD panel.

I've constructed a cable, crossed the pins etc. Got the contrast and backlight working, but my synth (qs7) goes silent/hisses when the new display is connected. The display shows the default HD44780 all solid bars across the top line for not initializing. If I plug in the old dead display, everything is fine (execpt displaying characters)

Anyone here know how to solve this. Please help
